Why it works: Onion and beef are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 17,092 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Eggs, Curried
Ingredients
Directions
Make the curry base
Fry the sliced onions in butter until brown.
Add curry powder and beef broth, then stew until the onions are tender.
Finish and serve

Slice the hard-boiled eggs and add them to the stew.
Let the eggs warm in the stew, but do not boil.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Onions
- Soften and sweeten as they stew, forming the flavour base of the sauce.
- Butter
- Fat that browns the onions and carries the curry flavour.
- Curry powder
- Supplies the spiced aroma that defines the dish.
- Flour or cornstarch
- Thickens the broth into a body-rich sauce that clings to the eggs.
- Hard-boiled eggs
- Provide the main protein and soft texture in the stew.
The step that matters
Warming the eggs without boiling. Boiling the stew can toughen the egg whites and make the yolks grainy or rubbery. Gentle heat warms the eggs through while keeping them tender and intact.
Swap the onion
How well each one fits the dish's main ingredients (butter, beef, flour, egg):
- Chivefits better
- Leekfits better
- Shallotfits better
- Onionthe original
Fit is the average pairing score against butter, beef, flour, egg. Candidates are from the same food group and used in at least 100 recipes.
